SAFETY DEVICE FOR WINDOWS Filed July 11, 1932 INVENTOR,

ATTORNEY.

Patented May 16, 1933 UNITED STATES LEWIS H. Been-or SPRINGFIELD, MASSACHUSETTS SAFETY DEVICE FOR WINDOWS Application filed July 11,1932. Serial No. 621,839.

My invention relates to improvements in safety devices for windows, and more par ticularly to that type of window'which is provided with an operable or slidable sash.

An object of my invention is to provide means for blocking or obstructing the opening in a window frame, when the sash memher, which is installed in the frame, is operated to produce such an opening, for ventilation or other purposes, thus preventing the entrance of any intruder from the outside when the sash is opened or raised, either a partial or full opening. A further object ofrmy invention is to provide such an obstructing or blocking means, which is attached to and follows the sash in its movements, thus automatically adjusting itself to any opening caused by operation of the sash.

Broadly, my invention comprises, in combination with a window frame and window sash slidably installed therein, a suppleing where protection of this nature is con-' sidered necessary or advisable, and may be installed to operate either vertically or horizontally.

In the accompanying drawing:

1 Referring, to the drawing in detail, in which like numerals refer to like parts throughout. I

The double hung window frame 1, comprising the side jambs 2, head jamb, 3, stool 4, and sill 5, has installedtherein, in the usual manner, the upper sash 6 and lower sash 7. Secured in the lower part of the window opening, on the inside, adjacent to the lower sash 7 is the metal-channel-shaped supplemental frame 8, having theside members 9, bottom member 10, and top member 11. The top member 11 is approximately level with the meeting rails 12 and 13 of the sashes 6 and 7, respectively. The side members 9 are secured to the-side jambs 2', by means of screws 14. Hinges 15, secured to the bottom member'lO by spot welding or other suitable means, are secured in' rabbets 16 formed in the stool 4 by screws 17. Supportingmembers'18 and 19 are'sli'dably secured in the channels of the side members 9, and the lazy-lever construction comprising the links 20, 21, 22, 23, 24, and 25 are pivotally secured to the bottom member 10 and to the supporting members 18 and 19 at 26, 27, and 28. The bottom member 10 is formed with a slot 10 in its top surface extending the full width of the frame 8, and the supporting member 18 is formed withia corresponding slot 18 in its bottom portion. The supporting member 19 is formed witha similar slot in both of its top and bottom portions, as shown, thus permitting 'free'moveinent of the links 20, 21, 22, 23,- 24, and 25,

'into and'out of these slotted'members during the upward and downward movementsof the links. Outwardly extending pins 29, se

u 1 cured to the member 18 in anysuitable man- Fig. 1 is an elevat1onal View showing my ner, such as welding or riveting, are located in the sockets 30 let into the bottom rail 31 -ment of the sash 7 will carry with it the supporting member 18 and, through action ofthe connected links,the middle supporting member 19. The frame 8, in combination with the members 18 and 19 and links20 to ash 7-, Howemr, anyisuitableimeans or. raismgthe sash- 7, such ,as a;- window- .pole} and socket, will serve to operate the'safety device as well.

In. Fig. 3, thersash,7uisjilust a ed in-i sa closed position, in which position the intermediate movable member 19 irests on lithe-Q fixed bottom member 10 andthe upper movable member 18 rests on the m einber 19,-thus a, completely enclosing the links 20 to inelusive, as shown, and presenting a neateand smooth appearance. The, screw means 14 and 17, for securing the rectangular frame 8 to the window frame, are inaccessiblefrom. ,.,.the outside.
